Alice Springs Desert Park, in NT, Australia, recently welcomed a Thorny Devil hatchling in the Park’s Nocturnal House.
The Thorny Devil (also known as a ‘Thorny Dragon’, ‘Thorny Lizard’, or the ‘Moloch’) is a species that is native to the dry desert and shrub land of Australia. The average adult reaches a length of 15 to 20 cm (5.9 to 8 inches), and will weigh about the same as a mouse (a max of about 95 g or 3.4 oz). They are known to have an average life span of 12 to 20 years.
Thorny Devils are a difficult species to breed in captivity because they will only breed when in excellent condition, which requires keeping them very well fed on a diet of ants throughout winter, until ready for spring breeding. Incubation at the Alice Springs Desert Park took 3 months, at 29 degrees. Time period for incubation varies according to temperature.
Hatchlings are completely independent and soon after hatching, they start eating ants. Surprisingly, it will take 2 years for the young to reach full adult-size.
As with many species of lizard, the female Thorny Devil is slightly bigger than the male and tends to be slightly paler in color. All Thorny Devil individuals tend to change from a paler to a darker color when they cool down.
The Thorny Devil also has a pretend head at the back of its neck which is used to mislead oncoming predators. It will dip its real head down, when threatened, and will therefore have a slight advantage on other animals.
The new addition, at Alice Springs Desert Park, is an exciting achievement for their reptile team. The last time Thorny Devils bred at the Desert Park was in 2008.
